I claim: A MQGRENG QUNHNG 1, A marine piling mooring structure comprising 21 Joseph E. Voilmar, J12, Ladue, Mm, assignor to Vollmar Brothers Construction Company, St. Louis, Mo., a corporation of Missouri Filed .lune 17, 1960, Ser. No. 36,833 2 Claims. (Cl. 114-230) The invention relates to mooring devices such as are used in tieing up vessels to a marine pier, particularly of the form consisting of a series of sheet piling sections with interlocked tongues and grooves spaced apart and with a straight web connecting them.

It has been customary to attach a mooring ring to a pier of this type by means of an I-bolt or U-bolt, and sometimes to weld the I-bolt or U-bolt to the outer face of the pier. Experience has shown that these attaching arrangements are not reliable, and among the objects of the invention is to provide an adequate anchoring of the mooring ring to the pier without resorting to expensive heavy rings and bolts, etc. This main object and other detail objects will be apparent from reference to the accompanying drawings and detailed description. In the drawings:

FIGURE 1 is a top view of a series of three pilings required for a pier of the type described, the mooring ring and its securing means being shown also.

FIGURE 2 is a side view of the mooring ring and its securing means.

FIGURE 3 is a vertical transverse section on line 33 of FIGURE 2.

FIGURE 4 is a horizontal transverse section on line 44 of FIGURE 2.

The pier piling units are of well-known form and each has a straight web section 1 with offset knuckles 3 as illustrated. A mooring ring 5 is mounted on the flat web of one of the piling sections by a U-shaped securing loop member 7. The bar stock for the mooring ring and the securing loop member are of substantially the same diameter. The opening through ring 5 has a diameter at least twice the cross sectional diameter of each of the legs of member 7. The ends of the loop member legs are welded to the web 9 of an elongated channel which also includes marginal flanges 10 extending from the inner face of the channel web and in the opposite direction from the loop. The channel is disposed lengthwise of the piling web and the edges of the channel flanges are welded directly to the piling flat web.

Preferably the legs of the U-section 7 project through openings in the channel Web and are welded directly to both sides of the channel web, as indicated by the weldments W, which encircle the U-legs and secure the same to both faces of the channel web. The length of the channel web is greater than the diameter of the mooring ring, plus the overall width of the U-mounting member, and since the edges of the channel flanges are welded directly to the piling web substantially continuously, the whole length of the channel itself provides extended joints between the U-member and the channel and between the channel and the piling web substantially longer and stronger than could be obtained by welding the U-bolt directly to the piling web, or by use of nuts threaded onto the ends of the U-mounting. The flanges 10 are spaced apart a distance less than the width of the U- shaped member 7 as shown in FIG. 2.

The advantages of the structure are obvious and it is also apparent that details may be varied without departing from the spirit of the invention and the exclusive use of such modifications as come within the scope of the claims is contemplated.

base member of channel cross section including a narrow elongated web and spaced apart marginal flanges extending from one face of the web, said flanges being fiat and terminating in generally parallel free edges spaced from said web, said free edges adapted to fit flush against the surface of a marine piling whereby the edges may be welded directly to the surface of the piling, an open end U-shaped securing member projecting from the opposite face of said web, said U-shaped member including spaced legs connected at one pair of adjacent ends by a bight portion, another pair of adjacent ends of said legs inserted into and projecting through openings in said web and welded directly to opposite faces of said web, said flanges being relatively close together and spaced apart less than the width of said U-shaped member, a closed ring passing through said U-shaped securing member and loosely suspended therefrom, said closed ring having an opening therethrough which has a diameter at least twice the cross sectional diameter of each of said legs, the length of the base member parallel to its flanges substantially exceeding the combined distance between said legs and outside dimension of said ring, and the legs defining a plane generally parallel to said flanges.

2. In combination with a marine piling having an exposed outer surface, mooring structure comprising a base member of channel cross section including a narrow elongated web and spaced apart marginal flanges extending from one face of the web, said flanges being flat and terminating in generally parallel free edges spaced from said Web, said free edges welded directly to the surface of the piling, an open end U-shaped securing member projecting from the opposite face of said web, said U-shaped member including spaced legs connected at one pair of adjacent ends by a bight portion, another pair of adjacent ends of said legs inserted into and projecting through openings in said web and welded directly to opposite faces of said web, said flanges being relatively close together and spaced apart less than the Width of said U-shaped member, a closed ring passing through said U-shaped securing member and loosely suspended therefrom, said closed ring having'an opening therethrough which has a diameter at least twice the cross sectional diameter of each of said legs, the length of the base member parallel to its flanges substantially exceeding the combined distance between said legs and outside dimension of said ring, and the legs defining a plane generally parallel to said flanges.
